Claims priority, application Sweden October-30, 1953'- Claims. (Cl. 166-59) This invention relates to apparatus for heating sub.- surface geological deposits in. situin their natural COlldltion in the ground for the purpose of recovering valuable substances in liquid and/ or gaseous state. Examples for sub-surfaces deposits in consideration are. shale strata, tar sand layers and sulphur deposits.

It is known in prior art to performthe heating bymeans of vertical holes or channels bored down frornthe surface on the earth into or otherwise produced in the de posit to be, heated. Said holes or channelsare entered by tubular heating members emitting their heat tov the surrounding part of the deposit. The heat may be generated in several ways, for example by electricity in the manner disclosed in the, French Patent No. 1,013,679. It is also possible to circulate aheat yielding mediumsuch as superheated steam, for example, throughtheheating member. A further possibility is to create a combustion in the heating member. This lastv alternative is particularly advantageous in the exploitation by heating of fuelcarrying deposits, since considerable quantities of combustible gases generated by. the heating process can be used directly as fuel in the continuing heating process. Said gases which otherwise are difficultto employ, in par-' ticular if they are of a composition making their condensation diflicult, can thus directly come to economic application instead of being burnt in a power plant producing electric energy which roundabout way would cause considerable losses of energy.

When placing a conventional-gas burner in the tubular heating member to be heated by combustion, the distribution of heat along the wall surrounding, or outer casing of the member will become very unequal, the portion adjacent the flame generated in the combustion becoming much more heated than other wall. portions, In the heating of deposits or strata in their natural condition it is a desideratum that the whole part of the heating rnember located in the deposit or stratum to be treatedis heated to at least approximatelythe same'temperature. Inorder to accomplish such equal distributionv of heat. generation of a plurality of flames on differentlevels has been proposed in the above cited French patent. It has proved diflicult, however, to attain for each; flame the most appropriate proportion between the quantities sup.-. plied of gaseous fuel and combustion-sustaining medium such as air or oxygen.

In order to overcome said inconvenience, one primary object of the invention is to provide a heating apparatus of the type specified with means for supply of fuel and combustion-sustaining medium to each fiarne'in suitable proportions for ensuring a combustion by which the .wall

of the heating member is heated uniformly over a predetermined length.

A fuither object of the; inventionis. to provide an a'p-- States Patent 0 2,890,754 Patented June 16, 1-959 paratus of the type specified with means adapted to produce thorough intermixture of gas and combustion-sustaining medium supplied to each of the flames in order to ensure complete combustion.

Further objects and advantages of the invention will be apparent from the following description considered in connection with the accompanying drawings which form part of this specification and of which Fig. 1 is a side view of an apparatus embodying the invention, part of the outer wall or casing being cut away.

Fig. 2 is a cross-sectional view of the apparatus shown in Fig. 1 but presented in an enlarged scale.

Fig. 3 is a sectional view following line Ill-4H of Fig. 2.

Referring to the drawings and in particular Fig, 1, the apparatus has aplurality of annular burner members generally denoted by 10 and located-in the interspace between an outer wall or casing 1-1 encasing said burner members and an inner wall. or tube 12 disposed substantially concentrically with the outer wall or casing 11; The spacing of the burner members it) from one another is dependent on the distribution of heat desired along the outer casing 11.

It may be mentioned that thecasing 11 and the tube 12 are presented in Fig. l in different scales with respect to their vertical and horizontal dimensions. In the vertical dimension, said members may in reality often have a length of about 20 metres, for example, whereasin' the horizontal dimension the outer diameter of the casingwill as a rule be less than 10 centimetres.

The tubular outer casing 11 is sealed on both ends, but adjacent the upper end which is intended to remain above the surface of the earth, said casing is provided with a connecting tube 13. From the same end of the casing 11 the upper end of the inner tube 12 projects upwardly. This projection is provided with two connecting tubes denoted by 14 and- 15, respectively, and opening into the tube 12 at diametrically opposite points.

As will. be seen from Fig. 3, the tube 12 is subdivided by a longitudinal partition 16 into two channels 17 and 18, respectively, of which the one channel communicates with one and the other channel with the other connecting tube 14 or 15, respectively.

The burner member lll is a hollow annular body carrying a plurality of nozzles. The annular body is in sealing connection attached to the inner tube 12-, but has no larger radial dimension than to leave a free annular space between its outer periphery and the outer casing. 11. The member 10 is composed of three parts, viz. an upper part 19, a lower part 2'0 and an intermediate part. 21L. The. nozzles are disposed in groups eachof which comprises two'nozzles located the one within the other. Fig,

3 presents four groups of said type disposed on one an nular burner member, but it is to be understood that more or less than four groups of nozzles may be applied onto one burner member. Of the two nozzles belongingto each group, the one designated by22 has alarger diameter thanthe other designated by 23, as willibe apparent approximately the same from Fig. 2. Both nozzles have longitudinal dimension and are centrically theone. within the having the lesser diameter aredisposed so as to'extend placed substantially condiameter.

penetrates through the intermediate part 21.v Due to the cup-like shape of the lower part20. an annular. passage 24' is formed, the narrower nozzles 23 communicating with said, passage which also communicates. with .tl1e channels 18' lbyholes 25 disposed in the wall of the inner tube 12.

other, but the nozzles 23.

The wider nozzles 22 are rigidly secured to the upper part 19 and open into an annular passage 26 formed due to the cup-like shape of said upper part 19. The intermediate part 21, too, comprises an annular passage 27 which by a plurality of holes 28 communicates with the passage 26 in the upper part 19. Finally, the annular passage 27 communicates with the channel 17 by holes 29 disposed in the wall of the inner tube 12.

In operation of the heating device described above, fuel which preferably is a combustible gas, is supplied to the channel 17 through the connecting tube 14. From said channel 17 the fuel is fed to the various annular burning members 10. In each individual burning member the fuel is distributed by means of the annular passage 27 from which the fuel is introduced through the holes 28 into the annular passage 26 located thereabove and passes finally through the interspace between the narrower nozzle 23 and the wider nozzle 22. The holes 29 which are the first to be passed by the fuel are rather large for which reason a moderate throttling only of the flow of fuel is created there. The following holes 28 are considerably minor and provoke a more effective throttling. By said throttling measures the ditferences in pressure existent in the channel 17 are almost wholly equalized so as to ensure practically the same pressure of the fuel when supplied to the annular burner members irrespective whether their location is the highest or the lowest one on the tube 12 in the apparatus. The annular passages 26 and 27 have a pressure equalizing eifect in the lateral direction so as to impart the same pressure to the fuel in each of the nozzles of the same burner member. Due to their small diameter the holes 28 enable such holes to be provided on the same level around the inner tube 12 in relatively large number. This arrangement affords additionally to the equalization of the pressure of the fuel supplied to the burner members the further advantage of ensuring undisturbed operation, if one or several holes should be clogged by solid particles carried along by the fuel, since the remaining holes are suflicient for permitting the flow of fuel to pass without any appreciable variation in pressure being created.

The combustion-sustaining medium is supplied in the form of air, for example, through the connecting tube diametrically opposed to the connecting tube 14 through which the fuel is introduced. The air is distributed through the channel 18 to the individual annular burner members 10. It is permitted to penetrate into said members through the holes 25 opening into the annular passage 24. In this annular passage the air is distributed and finally escapes through the narrower nozzles 23. As far as the combustion-sustaining medium, such as air, is concerned, additional throttling holes are not necessary, because the holes 25 provided in the wall of the inner tube 12 can directly produce the required throttling effect. A relatively large number of said holes may be disposed and each individual hole may be given a correspondingly small diameter, since the channel 18 for the supply of the air has a larger cross-sectional area than the channel 17 for the supply of fuel, which relation is due to the necessity to supply a larger volume of air than fuel per unit of time in order to obtain complete combustion.

Upon ignition a flame will be formed in the broad nozzles 22. The primary object of said nozzles is to protect the flame from disturbances which otherwise easily would be caused by flue gases escaping from burner members located on a lower level. As is well known a flame is easily extinguished when becoming subjected to the influence of other gases having a high flow velocity. The.

diameters of the wide and the narrow nozzles have been dimensioned relatively to one another so as to obtain a suitable proportion between the flow velocities of the fuel and the air, respectively. The flue gases resulting from the combustion are allowed to pass through the inter-- space between the inner tube 12 and the outer casing 11 and to escape through the connecting tube 13. During 4 V I said passage the flue gases yield part of their heat to the outer casing 11. The distribution of the heating temperature produced thereby is dependent on the manner of spacing the annular burner members from one another. If a substantially equal temperature is to be produced along the tubular casing 11, the burner elements 10 must be placed nearer to one another at the bottom than at the top of the casing, since near the top the flue gases from the bottom, too, contribute in the heating. Another possibility of adjusting the distribution of temperature consists in varying the number of groups of nozzles provided on each individual burner member. It may also be suitable to provide one or several portions of the outer casing 11 or/and the inner tube 12 with a protection against radiation or other suitable heat insulating means. Such protection is particularly desirable about the flames as well as that portion of the outer casing adjacent the earth surface. This portion is often desired to be prevented from becoming heated, since the surrounding geological formations usually are gravel or lime stone which are incapable of yielding valuable products when heated.

The heat remaining in the escaping flue gases may suitably be used for different purposes, such as preheating of the fuel and the air, preheating of deposit not yet heated, and fractional distillation of products recovered. For such heat recovery heat exchangers of well known constructions may be used, said exchangers being located either above-ground or below the surface in assembly with the heating apparatus in which latter case it preferably comprises the portion thereof desired to remain unheated.

The fuel need not be in gaseous form, it may be completely or partly replaced by liquid or solid finely distributed fuel. The combustion-sustaining medium may instead of air completely or partly be constituted by oxygen or another oxygen-containing gas mixture than air.

While a preferred embodiment of the invention has been described above, it is to be understood that this is for the purpose of illustration only and that the invention is not to be limited thereby, but its scope is to be determined by the appended claims.
